Peeing all day is not necessary. I drink about 64oz tops and I mean it's rare I get near that. 1 gallon? Jeez guys.
1 Gallon = 128oz = 16 glasses of water. I'm guessing 95% of this board drinks between 0-0.5 gallons of water, this poll is skewed. How the hell do you all find time to drink a gallon of water?!?!?!
I drink around 6 bottles of water daily. At first I would pee all the time. That has changed now since my body has gotten used to it.
As long as your pee isn't dark yellow color or anything, you should be good. Ideal would be clear colored.
